[Bug libfortran/18879] New: ? not supported in namelist input

["Thomas dot Koenig at online dot de" <gcc-bugzilla at gcc dot gnu dot org>]

A ? as input should dump the variable names of the namelist
to standard output.

Like PR 18874, but with libfortran.

$ cat namelist.f90
program main
  namelist /foo/ a
  read (*,foo)
end
$ gfortran namelist.f90 && ./a.out
?
At line 3 of file namelist.f90
Fortran runtime error: Invalid character in namelist
$ gfortran -v
